Folks bring their kids all the time, judging by pictures and accounts of the events. You might have a chat with them about asking before they approach strange dogs though...I've heard that you get the occasional jackass who brings his big bad tough poorly tempered pit bull to pulls...but as long as you think they can be respectful of strange dogs I don't see a reason not to bring kiddos. If they are under the impression that all dogs are like Summer though...maybe not.
